The Lowdown
Alright folks, Rusty here with a look at what’s coming down the pipe. Hang on, because this forecast for Jaconé has a lot of moving parts, and we’ve got a massive swell coming that we need to talk about.
First up, the water temp is sitting at a warm 73°, which is about 1° warmer than average for the time of year. Nothing too unusual, just a touch of extra tropical warmth in the water.
Alright, so the pattern. This one starts quiet. The weekend is a write-off; Saturday morning has a tiny 2ft SSE swell with glassy conditions, but the energy is weak (125) and it’s just too small to get excited about. Winds go bad in the afternoon, and Sunday is a complete mess with strong onshore winds and a rising, lumpy south swell. We’re not surfing that.
Monday the 7th, though, we start to see a real shift. The morning is still average with a bit of cross-onshore wind, but Monday afternoon is the first real standout. The wind goes dead calm and glassy, the swell is a solid 8ft from the SSW, and the energy is cranked up to a strong 1055. This is excellent, expert-level surf. The size is over 8ft, so this is strictly for the experienced crew. The beach setup here might mean it’s a bit straight, but with that glassy texture, it’s going to be a session to remember.
Tuesday the 8th morning keeps the quality going with a clean 5ft SSE swell and a moderate offshore wind from the NE. Good energy (910), and a much more manageable size for the intermediate surfer. That’s your best bet if you’re not a pro.
Now, we have to talk about Monday the 14th and 15th. There is a monster pulse of swell predicted. Monday brings a massive 13ft S swell with a very long period of 13 seconds, and the energy is through the roof at 5387. However, the guidance flat-out says the swell is too big for this break. The winds are light, the conditions would be perfect, but it’s an absolute beast that will be washing through. This is a "watch from the cliff" day unless you are a big-wave charger with the right gear, and even then, Jaconé might not handle it. Tuesday the 15th morning is still very large at 7ft but with clean offshore winds, making it another expert-only session.
After that big pulse, we settle back into a more consistent pattern from Wednesday the 16th morning through to Sunday the 20th. The standout in this second week is Wednesday the 16th morning – a clean, glassy 4ft SE swell with light winds. Also, Sunday the 20th morning looks very promising with a clean 6ft ESE swell and a light offshore breeze. That’s a beauty for everyone.
Keep in mind, this place is listed as consistent, and for a long stretch there, it delivers. The crowd situation can be a problem at times, so get out early.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
